First substitute .5x in for y to get a solvable equation. You should get 6x+8(.5x)=30. Then multiply 8 times .5 to get 6x+4x=30. Then combine like terms (6x+4x) to get 10x=30 and divide both sides by 10 to get x=3. Then plug this x value (3) into the other equation (y=.5x) to find the value of y. Y=.5(3) so y=1.5. Therefore the answer is B.
Answer:
40
Step-by-step explanation:
Answer:
C. $23 per day.
Step-by-step explanation:
The equation given is in slope-intercept form: y = mx + b, where m is the rate of change (slope).
In the given equation, m = 23, therefore, the rate of change is 23 units (in this case, dollars per day).
Hope this helps!
Slope = (y2 - y1) / (x2 - x1)
(-9,6)....x1 = -9 and y1 = 6
(-3,9)...x2 = -3 and y2 = 9
now we sub and solve
slope = (9 - 6) / (-3 - (-9) = 3 / (-3 + 9) = 3/6 = 1/2 <=
1/3 x pi x radius squared
1/3 x pi x 0.7225 = 0.7566002307
